Very nice! Designing the antenna to be located under the chassis will make a lot of people on this forum very happy. And the fact that the Metl Tech's will fit certain 1/64 diecast cars doesn't hurt. I still can't believe that this bit is reported to have 21 steps each way for the proportional steering. I'm sure one of my friends will buy one to race against my dual cell bit. It'll just give me an excuse to redesign it again.
I'm still curious about that funky controller. Is it designed to be used in one hand?
